Bio:Mercy was Henri LeBeau's wife and the first female master thief in Guild history. As such she had been given the Elixir of Life and aged much slower than normal, appearing to be in her 20's while in her 50's. It is clear that she worries about Remy from her few appearances.

She recently voted in the Vote of No Confidence that Theoren Marceaux and Gris-Gris called when Remy was leader of the Unified Guild, and unsurprisingly voted in Remy's favour.
